DETAILED DESCRIPTION OF THE DRAWINGS
[0185] Reference is made to FIGS. 1 to 3 which illustrate a
dispenser assembly 10 adapted to be secured such as onto support
structure such as to a wall or a stand as by a back plate, not
shown.
[0186] As seen in FIG. 4, the dispenser assembly 10 contains four
principal components, namely, a cover assembly 14, a cartridge 15,
a housing assembly 16 and a lifting or lifter member 500, also
referred to as a cover actuator member 500.
[0187] Reference is made to FIG. 4 which illustrates a cartridge 15
comprising a pump mechanism 100 and a fluid reservoir also referred
to as a containing bottle 101. As illustrated in FIGS. 25 and 26,
when the cover assembly 14 is in an upper open position relative to
the housing assembly 16, by relative horizontal movement of the
cartridge 15, the cartridge 15 may be moved horizontally forwardly
and rearwardly between a disengaged uncoupled condition in front of
the dispenser assembly 10 as seen in FIG. 26 and to a coupled
orientation seen in FIG. 25. With the cartridge 15 in the coupled
orientation as in FIG. 25, the cover assembly 14 may be moved
relative the housing assembly 16 from the upper open condition of
FIG. 25 to a lower closed position of FIG. 24 capturing the
cartridge 15 within the dispenser assembly 10 against removal in an
operative position for dispensing of fluid from the bottle 101 of
the cartridge 15 by activation of the pump mechanism 100 with a
lever 19. The cartridge 15 includes the pump mechanism 100 and the
fluid containing bottle 101 with the pump mechanism 100 and the
fluid containing bottle 101 being removable and insertable together
as the cartridge 15 independently. Thus what is referred to as a
removable member 666 may comprise the pump mechanism 100 and/or the
fluid containing bottle 101.
[0188] Reference is made to FIG. 23 illustrating a cross-sectional
view along longitudinal center line A-A' in FIG. 2 showing the
cartridge 15 coupled within the dispenser assembly 10 with the
cover assembly 14 in the lower closed position relative to the
housing assembly 16 in an operative condition ready for operation
of the dispenser assembly 10 to dispense fluid.
[0189] The bottle 101 is enclosed by four side-by-side side walls
102 and a bottom wall 103 and is open merely at an upper end
through an opening 104 at the top of a cylindrical neck 105
extending upwardly from a top wall 106. The pump mechanism 100
includes notably a piston chamber-forming body 110 and a
piston-forming element 111. The piston-forming element 111 is
coaxially slidable about a vertical axis 955 relative to the piston
chamber-forming body 110 to draw fluid from the bottle via a dip
tube 112 connected to the piston chamber-forming body 110 and
discharge the fluid from a downwardly directed discharge outlet 113
carried at the front end of a forwardly extending discharge tube
114 that extends forwardly from and is carried by the
piston-forming element 111.
[0190] The piston chamber-forming body 110 defines a fluid chamber
952 herein coaxially about the axis 955 open at an open upper end
and with a lower open end in communication with fluid in the bottle
101 via the dip tube 112 which extends downwardly to a fluid inlet
opening 954 open to the fluid in the bottle 101. The piston-forming
element 111 has a piston portion 953 received in the fluid chamber
952 with the piston-forming element 111 extending out of the open
upper end of fluid chamber 952 to the discharge outlet 113 carried
on the piston-forming element 111.
[0191] When the cover assembly 14 is in the raised upper position
relative the housing assembly 16 as seen in FIGS. 25 and 26, the
cartridge 15 is horizontally slidable rearwardly to engage with the
housing assembly 16 such that the bottle 101 comes to be received
within an interior 46 defined within the housing 70 with the bottom
of the bottle 101 engaged and supported by a bottle support flange
116.
[0192] The piston chamber-forming body 110 carries a horizontally
extending support plate 117 that extends radially relative the
axis, preferably normal to the axis 955 as shown, outwardly from
piston chamber-forming body 110 laterally to the left and the
right. External portions of the piston-forming element 111 extend
upwardly from the piston chamber-forming body 110 above the support
plate 117. The piston-forming element 111 is vertically slidably
engaged within the piston chamber-forming body 110 for coaxial
vertical reciprocal sliding about the vertical axis 955 and with an
internal spring (not shown) biasing the piston-forming element 111
vertically upward relative to the piston chamber-forming body
110.
[0193] As seen on FIG. 41, the support plate 117 has a forwardly
directed stopping surface 960, an upwardly directed plate surface
961, a downwardly directed plate surface 962 and a rearwardly
directed cam surface 964.
[0194] The cartridge 15 is adapted to be removed and replaced
preferably by a new entire cartridge 15 as seen in FIGS. 25 and 26,
however, possibly with the bottle 101 being removed from the
cartridge 15 and refilled. Removal and replacement of merely the
bottle 101 is possible such as illustrated in FIGS. 39 and 40 when
the dip tube 112 may be rigid the bottle 101 removed the pump
mechanism 100 may be separately removed and replaced. Removal and
replacement is carried out with the cover assembly 14 in the upper
open opposition relative the housing assembly as seen FIGS. 25 and
26.
[0195] As seen in FIGS. 5 and 6, the cover assembly 14 includes a
cover 18, the lever 19 and a rod member 20. Referring to FIG. 6,
the cover 18 includes a top wall 21, a right cover side wall 22 and
a left cover side wall 23. The right cover side wall 22 and the
left cover side wall 23 are secured together spaced laterally from
each other by being connected at an upper end by the top wall 21
and a lower end by the rod member 20. The rod member 20 is
preferably a cylindrical member bridging between the side walls 22
and 23 and each end of the rod member 20 is fixedly secured to a
lower portion 26 of each of the side walls 22 and 23. In the
preferred embodiment, the cover assembly 14 including the cover 18
and the lever 19 is each symmetrical about a central longitudinal
plane along section line A-A' in FIG. 2. Each of the side walls 22
and 23 has a top portion 24 and a lower portion 26 with an
intermediate portion 25 bridging between the top portion 24 and the
lower portion 26.
[0196] As best seen in FIGS. 8 and 9, in the top portion 24 of each
of the side walls 22 and 23, there is provided an identical axle
keyway opening 27 that extends laterally through the respective
side wall 22 and 23. Each axle keyway opening 27 has an enlarged
journaling bore 28 and entry/exit slot 29. Each slot 29 is open
into the bore 28, extends from the bore 28 to a rear edge 30 of
each of the side walls 22 and 23 where each slot 29 is open through
the edge 30.
[0197] The cover 18 about each slot 29 is resilient and has an
inherent bias to adopt an inherent configuration as shown in FIGS.
8 and 9. The cover 18 about each slot 29 is deflectable from the
inherent configuration to deflected conditions in which the slots
29 increase in width to permit the coupling and uncoupling of the
lever 19 with the cover 18.
[0198] Referring to FIG. 7, the lever 19 has an exterior handle
portion 32, an axle 31 and an interior actuator portion 33. The
exterior handle portion 32 comprises a U-shaped member with a
forward bight 34 which merges rearwardly into a right arm 36 and a
left arm 37. The right arm 36 is connected at its rear to an outer
right end 38 of a right segment 40 of the axle 31. The left arm 37
extends rearwardly to join with an outer left end 39 of a left
segment 41 of the axle 31. The axle 31 including both the right
segment 40 and the left segment 41 is coaxial about an axle axis
35. The interior actuator portion 33 includes a right activator rod
42 which extends forwardly from an inner right end 44 of the right
segment 40 of the axle 31. The interior actuator portion 33
includes a left activator rod 43 which extends forwardly from an
inner left end 45 of the left segment 41 of the axle 31. The right
activator rod 42 and the left activator rod 43 are disposed in the
same plane.
[0199] The lever 19 is removably coupled to the cover 18 by reason
of the axle 31 of the lever 19 being removably coupled within the
axle keyway openings 27 in the side walls 22 and 23. The bore 28 of
each keyway opening 27 is sized to receive the axle 31 of the lever
19 therein and journal the lever 19 for rotation of the lever 19
about the axle axis 35 relative the cover 18. The right segment 40
of the axle 31 is received within the bore 28 of the keyway opening
27 of the right cover side wall 22 and the left segment 41 of the
axle 31 is received within the bore 28 of the keyway opening 27 of
the left cover side wall 23.
[0200] The axle 31 is removably received within the bores 28 in a
snap-fit. The cover 18 about each slot 29 is resilient with its
inherent bias adopting the inherent configuration as seen in FIGS.
8 and 9 in which the slot 29 is sized to retain the axle 31 in the
bore 29 against removal. The cover 18 about the slot 29 is
deflectable from the inherent configuration to deflected conditions
which permit passage of the axle 31 through the slot 29 either into
or out from the bore 29 for coupling and uncoupling of the lever 19
and the cover 18. The axle 31 is received coaxially within the
bores 28 of the keyway openings 27 against removal under forces
less than a threshold force required to deflect the cover 18 about
each slot 29 from the inherent condition to deflected conditions
which permit passage of the axle 31 through each slot 29 for
removal of the axle 31 from the keyway openings 27 of the cover 18.
The cover assembly 14 is removably coupled to the housing assembly
16 for coupling and uncoupling of the cover assembly 14 to the
housing assembly 16 while the lever 19 is coupled to the cover 18.
After the cover assembly 14 is uncoupled from the housing assembly
16, the lever 19 and the cover 18 may be disengaged and separated
from each other by removing the axle 31 from the keyway openings
27.
[0201] The cover 18 defines an interior compartment 46 between the
right cover side wall 22 and the left cover side wall 23. When the
lever 19 is coupled to the cover 18 with the axle 31 journalled in
keyway openings 27, the interior actuator portion 33 is within the
interior compartment 46 coupled to the axle 31 and the exterior
handle portion 32 extends forwardly exterior of the interior
compartment 46. The lever 19 is removable from being coupled with
the cover 18 by rearward movement of the lever 19 moving the axle
31 rearwardly out of the keyway openings 27 through the rear edges
30 of the side walls 22 and 23, moving the interior actuator
portion 33 rearwardly from within the interior compartment 46 out
the open rear of the cover 18. The right arm 36 and the left arm 37
of the exterior handle portion 32 are spaced laterally so as to
permit the top wall 21 and top portions 24 of the side walls 22 and
23 of the cover 18 to pass downwardly and forwardly between the
right arm 36 and the left arm 37 to assist coupling and uncoupling
of the lever 19 with the cover 18. In the preferred embodiment, as
shown in FIG. 7, the cover 18 is open at a rear of the cover and
the keyway openings 27 are open to the rear edge 30 of the cover
18.
[0202] In alternative embodiments, however, the keyway opening 27
may open to an edge of each side wall that constitutes an upwardly
directed upper edge.
[0203] Referring to FIGS. 7 and 10, on the intermediate portion 25
of the right cover side wall 22, there is provided a right latch
member 48 and on the intermediate portion 25 of the left cover side
wall 23, there is provided a left latch member 49. Each of these

edge 755 of the lower bridging wall 754. Forward of the lower
bridging wall 754, downwardly directed holding surfaces 757 and 756
of the left and right side walls 753 and 752 are disposed in a flat
plane raised above the flat plane of a lower surface 758 of the
lower bridging wall 754 with the exception of two holding stop
members 781 and 782 are provided one on each of the left and right
side walls 753 and 752 to extend downwardly to the flat plane of
the lower surface 758. Each holding stop member 781 and 782
presents a respective rearwardly directed stop surface 981 and
982
[0210] From the rear wall 751, a hook member 784 extends rearward
as an upper bight member 785 carrying a catch wall 786. As seen on
FIG. 35, the catch wall 786 carries a rearwardly extending catch
member 787 carrying an upwardly directed catch surface 788.
[0211] As can be seen in FIG. 37, the upper pump holding member 508
is secured to the housing 70 with its hook member 784 having its
catch wall 786 disposed in the slotway 746 between the back wall
202 and the front wall 744, with the catch wall 786 biased into
engagement with the back wall 202 and with the catch member 787
having its upwardly directed shoulder 788 engaged on the downwardly
directed shoulder 743 of the back wall 202 so as to latch the catch
member 787 to the back wall 202 against relative movement in a
frictional snap-fit relation.
[0212] With the catch wall 786 secured to the back wall 202 the
upper pump holding member 508 forms a cantilevered arm having as
marked on FIG. 36 a rear portion 952 comprising the catch wall 786
fixedly secured to the housing 70, a resilient intermediate portion
951 comprising the upper bight member 785 and a distal forward
portion 950 comprising the upper pump holding member 508 forward of
the upper bight member 785. The resilient intermediate portion 951
is between the rear portion 952 and the distal forward portion 950
with the resilient intermediate portion 951 being resiliently
deflectable for movement of the distal forward portion 950 between
the lower position and the upper position relative the rear portion
952 fixed to the housing 70. The distal forward portion 950 carries
the downwardly directed holding surfaces 757 and 756 as well as the
holding stop members 781 and 782.
[0213] The resilient intermediate portion 951 formed by upper bight
member 785 has an inherent bias to assume an inherent condition and
is deflectable to deflected conditions against the inherent bias
such that when the resilient intermediate portion 951 is deflected
from the inherent conditions the inherent bias urges the resilient
intermediate portion toward the inherent condition. When the rear
portion 952 of the upper pump holding member 508 is fixed to the
housing 70, the inherent bias of the resilient intermediate portion
951 biases the distal forward portion 950 to the lower position and
movement of the distal forward portion 900 toward the upper
position results in the resilient intermediate portion 951 being
deflected to deflected conditions in which the inherent bias urges
the distal forward portion 950 to the lower position.
[0214] The upper pump holding member 508 is preferably injection
molded from a plastic material as a unitary element with the
plastic material suitably selected to provide the resilient
intermediate portion 951 as formed by upper bight member 785 with
the desired inherent bias. As can be seen on FIGS. 34 to 36, with
the upper pump holding member 508 including the intermediate
portion 951 as formed upper bight member 785 in its inherent
condition, the catch wall 786 extends forwardly towards the rear
wall 751 as the catch wall 786 extends downwardly away from the
upper bight member 785. However when the rear portion 952 of the
upper pump holding member 508 is fixed to the housing 70, as seen
in FIG. 37, upper bight member 785 is deflected to a deflected
condition in which the catch wall 786 extends parallel the rear
wall 751. Thus when the rear portion 952 of the upper pump holding
member 508 is fixed to the housing 70, the inherent bias of the
resilient intermediate portion 951 biases the distal forward
portion 950 toward to the lower position and movement of the distal
forward portion 950 toward the upper position results in the
resilient intermediate portion 951 being deflected to deflected
conditions in which the inherent bias urges the distal forward
portion 950 toward the lower position.
[0215] In the position of FIG. 37, due to the inherent bias of the
upper pump holding member 508 the stop members 781 and 782 are
biased downwardly into engagement with the support flange 204. The
left and right side walls 753 and 752 of the upper pump holding
member 508 are adjacent to vertical guide walls 120 and 121 to
permit and guide the relative vertical sliding of left and right
side walls 753 and 752 of the upper pump holding member 508 with
deflection of the upper pump holding member 508 about the upper
bight 785 of the hook member 784. The lower bridging wall 754 is
placed in engagement with the upper surface of the support flange
204. As can be best seen in FIG. 37, forward of the lower bridging
wall 754 there is defined above the support flange 204 a
horizontally extending slot 900 between the support flange 204 and
the lower surfaces 757 and 756 of the left and right side walls 753
and 752 of the upper pump holding member 508 sized to receive the
support plate 117 of the piston forming body 110 as seen in FIG.
41.
[0216] Reference is made to FIG. 38 which illustrates a raised
position to which, from the position of FIG. 37, the upper pump
holding member 508 is deflected against its inherent bias raising
the distal front portion 950 of the upper pump holding member 508
to be spaced upwardly from the support flange 204 and disposing the
lower surfaces 757 and 756 of the left and right side walls 733 and
752 of the upper pump holding member 508 to be disposed tilted
forwardly at an angle to the vertical. Such a configuration as is
shown in FIG. 38 can occur with the cover 18 in a raised upper
position and as seen in FIG. 40 the pump mechanism 100 urged
upwardly into the upper pump holding member 508 so that the support
plate 117 of the piston chamber-forming body 110 of the pump
mechanism 100 is engaged with front portion 950 of the upper pump
holding member 508 with the pump mechanism 100 tilted so as to
assume the same tilted condition as the forward portion 950 of the
upper pump holding member 508. As seen in FIG. 40 with the lifting
member 500 in an open position, the axis of the pump mechanism 100
and the dip tube 112 of the pump mechanism 100 each extends
forwardly as it extends downwardly and the bottle 101 may be slid
coaxially at an angle vertically downwardly and forwardly onto and
off of the dip tube 112 without interference with the remainder of
the dispenser 10 and notably the support ledge 116. The ability to
adopt the forwardly tilted configuration such as shown in FIG. 40
can be of assistance particularly insofar as the dip tube 112 may
be rigid metal and cannot be bent. As well, adopting the
configuration illustrated in FIG. 40 can also be of assistance in
replacing a complete cartridge 15.
[0217] When the piston pump mechanism 100 is coupled to the housing
70 with the upper pump holding member 508 in the lower position and
the support plate 117 located in between the upwardly directed
support surface 999 of the support flange 204 and the downwardly
directed holding surfaces 756 and 757 of the upper pump holding
member 508, applying upwardly directed forces to the upper pump
holding member 508 moves the upper pump holding member 508 to the
upper position. In this regard in use of the dispenser 10 with the
cover in an open position such as seen in FIG. 31, a user may
manually engage and move the forward portion of the upper pump
holding member 508 upwardly as indicated to a user by a preferred
indicia arrow 995 and the associated word OPEN marked on the
forward portion 950 of the upper pump holding member 508 as shown
merely on FIG. 34.
[0218] When the upper pump holding member 508 is in the upper
position, the piston pump mechanism 100 can be coupled to and
uncoupled from the housing 70.
[0219] As seen in FIG. 38 in the upper position, the downwardly
directed holding surfaces 756 and 757 of the upper pump holding
member 508 are spaced from the upwardly directed support surface
999 of the support flange 204 by distances greater than distances
the downwardly directed holding surfaces 756 and 757 of the upper
pump holding member 508 are spaced from the upwardly directed
support surface 999 of the support flange 204 in the lower position
of FIG. 37.
[0220] When as seen in FIG. 39, the piston pump mechanism 100 is
coupled to the housing 70 with the upper pump holding member 508 in
the lower position and the support plate 117 located in between the
upwardly directed support surface 999 of the support flange 204 and
the downwardly directed holding surfaces 756 and 757 of the upper
pump holding member 508: (a) with the downwardly directed holding
surfaces 756 and 757 of the upper pump holding member 508 in
engagement with the upwardly directed plate surface 961 of the
support plate 117 and (b) with the rearwardly directed stop
surfaces 981 and 982 of the holding stop members 781 and 782
engaged with the forwardly directed stopping surface 960 of the
support plate 117, applying upwardly directed forces to the piston
chamber-forming body 110 moves the upper pump holding member 508 to
the upper position maintaining the upwardly directed plate surface
961 of the support plate 117 engaged with the downwardly directed
holding surfaces 756 and 757 of the upper pump holding member 508
and the rearwardly directed stop surfaces 981 and 982 of the
holding stop member engaged with the forwardly directed stopping
surface 960 of the support plate 117, tilts the piston-chamber
forming body 110 to having a lower end of the piston-chamber
forming body 110 move forwardly while maintaining the
piston-chamber forming body 110 to extends through the slot 205 of
the support flange 204.
[0221] As seen in FIG. 41, with the cover 18 in the closed position
a downwardly directed surface 954 of the top wall 21 of the cover
18 engages an upwardly directed surface 720 of the bridge member
722 of the upper pump holding member 508 to prevent upward movement
of the upper pump holding member 508. When the cover is in an open
position, the cover 18 and the downwardly directed surface 954 of
the top wall 21 of the cover 18 is spaced vertically upwardly above
the upwardly directed surface 720 of the bridge member 722 of the
upper pump holding member 508 that the upper pump holding member
508 may move upwardly to the upper position.
[0222] As seen in FIG. 37, the upper pump holding member 508 is
carried on the housing 70 above the support flange 204 to present
the downwardly directed holding surfaces 757 and 756 of the upper
pump holding member 508 in opposition to the upwardly directed
support surface 999 of the support flange 204. As seen in FIG. 39,
when the piston pump mechanism 100 is coupled to the housing, the
piston-chamber forming body 110 extends through the slot 205 of the
support flange 204 with the support plate 117 located in between
the upwardly directed support surface 999 of the support flange 204
and the downwardly directed holding surfaces 757 and 756 of the
upper pump holding member 508. More particularly, when the piston
pump mechanism 100 is coupled to the housing 70 with the upper pump
holding member 508 in the lower position, the support plate 117 is
captured against removal between the upwardly directed support
surface 999 of the support flange 204 and the downwardly directed
surfaces 756 and 757 of the upper pump holding member 508, with the
upwardly directed support surface 999 of the support flange 204
engaging the downwardly directed plate surface 962 of the support
plate 117 and the downwardly directed surfaces 756 and 757 of the
upper pump holding member 508 engaging the upwardly directed plate
surface 961 of the support plate 117, preventing vertical movement
of the support plate 117 relative the housing, and locating the
pump mechanism 110 in an operative position for engagement of the
piston-forming element 111 by the actuator mechanism 19.
[0223] As seen on FIG. 39, the rearwardly directed stop surfaces
981 and 982 of the holding stop members 781 and 782 of the upper
pump holding member 508 engage with the forwardly directed stopping
surface 960 of the support plate 117 when the downwardly directed
holding surfaces 756 and 757 of the upper pump holding member 508
are in engagement with the upwardly directed plate surface 999 of
the support plate 117 to prevent forward sliding of the support
plate 117 relative the upper pump holding member 508.
[0224] As seen on FIG. 38, forward of the upwardly directed support
surface 999 of the support flange 204, a support stop member 998 is
provided with a rearwardly directed stop surface 997 for engagement
with the forwardly directed stopping surface 960 of the support
plate 117 when the upwardly directed support surface 999 of the
support flange 204 is in engagement with the downwardly directed
plate surface 962 of the support plate 117 to prevent forward
sliding of the support plate 117 relative the support flange 204,
as occurs for example in FIG. 39.
[0225] As seen in FIG. 38, with the upper pump holding member 508
in the upper position, a forward entrance opening 991 is defined
between a forward end 992 of the upper pump holding member 508 and
the front edge 206 of the support flange 204. In the upper position
of FIG. 39 the piston pump mechanism 100 can be coupled to and
uncoupled from the housing 70 with: (a) the piston-chamber forming
body 110 moving through the slot 205 of the support flange 204 via
the slot opening in the front edge 206 of the support flange 204
and (b) the support plate 117 moving from forward of the upper pump
holding member 508 and the support flange 204 through the forward
entrance opening 991 to between the upper pump holding member 508
and the support flange 204.
[0226] As seen in FIG. 37 with the upper pump holding member 508 in
the lower position, the forward entrance opening 991 of FIG. 38 is
closed by engagement between the forward end 992 of the upper pump
holding member 508 and the front edge 206 of the support flange 204
and a forwardly opening horizontally extending entrance guideway
slot 990 is defined forward of the closed forward entrance opening
992 between an upper guideway surface 993 on the forward end 992 of
the upper pump holding member 508 directed at least partially
downwardly and a lower guideway surface 994 on the front edge 206
of the support flange 204 directed at least partially upwardly. At
least one of the upper guideway surface 993 and the lower guideway
surface 994 is also being directed at least partially forwardly so
that the forwardly opening horizontally extending entrance guideway
slot 992 has a vertical height that reduces rearwardly toward the
closed forward entrance opening 991. Preferably, as shown on FIG.
38, both the upper guideway surface 993 and the lower guideway
surface 994 are also directed at least partially forwardly.
[0227] On rearward movement of the cartridge 15 carrying the piston
pump mechanism 100 relative to the housing 70, as seen on FIG. 26
with the rearwardly directed cam surface 964 of the support plate
117 disposed horizontally in the forwardly opening horizontally
extending entrance guideway slot 990, engagement between the cam
surface 964 and the upper guideway surface 993 alone or between the
cam surface 964 and the upper guideway surface 993 and the lower
guideway surface 994 applies upwardly directed forces to the upper
guideway surface 993 which moves the upper pump holding member 508
toward the upper position opening the forward entrance opening 990.
The opening of the forward entrance opening 990 permits subsequent
rearward movement of the piston-chamber forming body 110 through
the slot 205 of the support flange 204 via the slot opening in the
front edge 206 of the support flange 204 and subsequent rearward
movement of the support plate 117 between the upper pump holding
member 508 and the support flange 204.
[0228] Preferably, as shown on FIG. 37, the upper guideway surface
993 is directed forwardly and downwardly and the lower guideway
surface 994 is directed forwardly and upwardly. With the upper pump
holding member 508 biased downwardly toward the lower position
relative the support flange 204 by a user merely manipulating the
cartridge 15 horizontally in the forwardly opening horizontally
extending entrance guideway slot 990, engagement between the cam
surface 964 of the support plate 117 and the upper guideway surface
993 and the lower guideway surface 994 permits the support plate
117 to move rearwardly and be captured between the upper pump
holding member 508 and the support flange 204 as in FIG. 39.
[0229] As seen in FIGS. 22 and 23, the cartridge 15 comprising the
bottle 101 and the pump mechanism 100 are received within the
housing in the interior or interior compartment 46 of the housing
70 and with the lifting member 500 in the closed position and the
cover 18 in the closed lower position. As seen on FIG. 12, the
housing 70 has a forward opening 899 providing access to the
interior 46 of the housing including the interior compartment
46.
[0230] The lifting member 500, when in the closed position, covers
a lower portion of the forward opening of the housing and, from the
closed position, the lifting member 500 moves downwardly relative
the housing to the open position in which a lower portion 898 of
the forward opening 899 of the housing 70 is not covered by the
lifting member 500. The lifting member 500, when in the closed
position, covers the lower portion 898 of the forward opening 899
of the housing 70 preventing removal of the cartridge 15 and its
removable bottle 101 from the interior 46 of the housing.
[0231] When the cover assembly 18 is in the closed lower position,
it covers an upper portion 897 of the forward opening 899 of the
housing 70 and, from the closed lower position, the cover assembly
18 moves upwardly relative the housing 70 to the open upper
position in which the upper portion 897 of the forward opening 899
of the housing 70 is not covered by the cover assembly 18. When the
cover assembly 18 is in the closed lower position, the cover
assembly 18 covers the upper portion 897 of the forward opening 899
of the housing 70 preventing removal of the pump mechanism 100 from
within the interior of the housing 70 through the forwardly open
upper portion 897.
[0232] With the lifting member 500 in the open position and the
cover assembly 18 in the open upper position, the bottle 101 and
the pump mechanism 100 are insertable into and removable from the
interior of the housing 70 via the forward opening of the
housing.
[0233] With the lifting member 500 in the closed position and the
cover assembly 18 in the closed lower position, the lifting
mechanism 500 and the cover assembly 18 together best prevent
removal of the bottle 101 and the pump mechanism 100. When the
lifting member 500 is in the closed position covering the lower
portion 898 of the forward opening 899 of the housing 70 and the
cover assembly 18 is in the closed lower position covering the
upper portion 897 of the forward opening 899 of the housing 70, a
viewing opening 959 as marked on FIGS. 1 and 3 is provided into the
interior compartment 46 of the housing 70 between the lifting
member 500 and the cover assembly 18 intermediate the lower portion
898 of the forward opening 899 of the housing 70 and the upper
portion 897 of the forward opening 899 of the housing 70 as shown
on FIG. 12. The viewing opening 959 is useful as for a user to see
the presence or absence of a bottle 101 or pump assembly 110 and
the contents in the bottle 101.
[0234] The provision of the upper pump holding member 508 is a
preferred arrangement for providing for tilting or pivoting of the
pump mechanism 100 and/or the entire cartridge 15 forwardly
relative to the housing 70 as can been advantageous for insertion
and removal. Various other arrangements may be provided which on
one hand secure the cartridge 15 and/or its pump mechanism 100 to
the housing 70 when the cover 18 is closed yet permit the pump
mechanism 100 and/or the cartridge 15 to be moved upwardly or
pivoted forwardly relative to the housing 70 to render insertion
and removable to the cartridge 15, and/or the bottle 101.
[0235] The housing right and left side walls 200 and 201 carry
vertically extending channels 214 and 215 which are to receive
laterally extending left and right slide members 216 and 217 on the
pump actuator plate 75 so as to couple the pump actuator plate 75
to the housing 70 for relative vertical sliding. The right and left
plate springs 76 and 77 are disposed between the support flange 204
and the pump actuator plate 75 to bias the pump actuator plate 75
to an upper position in the channels 214 and 215 and to permit but
resist downward movement of the actuator plate 75 to lower
positions within the channels 214 and 215.
[0236] FIGS. 22 and 23 illustrate the dispenser assembly 10 in an
operative condition ready for use to dispense fluid, however, with
the cover 18 in cross-section.
[0237] Referring to FIGS. 13 and 17, each of the right and left
housing side walls 200 and 201 carry a respective right and left
rod receiving slotways 260 and 261 open at open ends 266 and 267 in
bottom edges 262 and 263 of the housing side walls 200 and 201 and
extending vertically upwardly to respective blind ends 264 and 265.
The rod receiving slotways 260 and 261 are sized so as to receive
the rod member 20 of the cover 18 therein and locate the right
cover side wall 22 laterally to the right outwardly of the housing
right side wall 200 and the left cover side wall 23 laterally to
the left outwardly of the housing left side wall 201. When the rod
member 20 is within the rod receiving slotways 260 and 261, the
slotways 260 and 261 engage the rod member 20 and guide relative
sliding movement of the rod member 20 relative to the housing 70.
The rod member 20 may pass inwardly and outwardly through the open
ends 266 and 267 of the slotways 260 and 261 to disengage the rod
member 10 from the slotways 260 and 261 or to engage the rod member
20 in the slotways 260 and 261. The housing 70 is symmetrical about
the longitudinal central axis A-A' in FIG. 2 with each of the right
and left housing side walls 200 and 201 being mirror images of the
other.
[0238] Referring to FIGS. 12 to 17, each of the left and right
housing side walls 200 and 201 carry a respective right and left
lifter axle receiving slotway 510 and 511 closed at respective
forward ends 512 and 513 and have respective rear ends 514 and 515
with respective upper and lower camming surfaces 518 and 519 and
520 and 521 defining the respective slotways therebetween. As will
be described later, the lifter axle receiving slotways 510 and 511
are adapted to receive respective right and left stub axles 522 and
523 of the lifting member 500. Each of the slotways 510 and 511
extend slightly downwardly as each extends rearwardly.
[0239] As seen in FIGS. 13 to 17, on the right housing side wall
200, there is provided a rod-like stop button 524 which extends
laterally away from the right side wall 200. Also provided on the
right housing side wall 200 to extend laterally to the right away
from the right housing side wall 200 is a right guide flange 530.
The left housing side wall 201 is a mirror image of the right
housing side wall 200 and, similarly as seen on FIG. 15, on the
left housing side wall 201, there is provided a rod-like stop
button 525 which extends laterally away from the left side wall 201
and a left guide flange 531 extending laterally to the left from
the left side wall 201 which is an identical mirror image of the
right guide flange 530 on the right housing side wall 200.
[0240] Referring to FIG. 16, rearward of the rod receiving slotway
260, the right side wall 200 is provided with a rear guide member
532 which extends laterally to the right of the right side wall 200
so as to present a downwardly directed stop shoulder 534 and a
forwardly directed cam shoulder 536. Similarly as seen on FIG. 15,
on the left housing side wall 201, there are provided mirror image
identical elements, namely a rear guide member 533 which extends
laterally to the left of the left side wall 201 so as to present a
downwardly directed left stop shoulder 535 and a forwardly directed
left cam shoulder 537.
[0241] Reference is made to FIGS. 19 to 21 which illustrate the
lifting member 500 which is seen to be generally U-shaped having a
central forward portion 540 disposed generally vertically on the
dispenser assembly 10 in a closed position. The lifting member 500
is symmetrical about the center plane A-A' in FIG. 2 with a right
arm 542 disposed in a generally vertical plane extending rearwardly
from a right side 544 of the central forward portion 540 and a
mirror image left arm 541 extending forward generally vertically
from the left side 545 of the central portion 540. The right stub
axle 522 extends laterally inwardly towards the left from the right
arm 542 and the left stub axle 523 extends laterally inwardly to
the right from the left arm 543. The right arm 542 as an upper
surface 560, an end surface 562 and a lower surface 564. Similarly,
the left arm 543 has an upper lower surface 561, an end surface 563
and a lower surface 565. Proximate the forward end of the right arm
542, a right hook portion 570 extends upwardly defining a
rearwardly extending hook member 572 extending rearwardly above a
bight 574. The hook portion 570 extends downwardly from the bight
574 to merge with the upper surface 564. Similarly, the left arm
543 includes a hook portion 571 with a hook member 573 and a bight
575.
[0242] Reference is made to FIGS. 13, 14, 17 and 18 to describe
left and right slide grooves 270 and 271 which extend laterally
through the respective left and right housing side walls 200 and
201 rearward of the back wall 202 of the housing 70. Each of the
slide grooves 270 and 271 extend vertically from bottom ends 276
and 277 to top ends 278 and 279. Each of the slide grooves 270 and
271 has a rearwardly directed front surface 280 and 281 disposed in
the same flat vertical plane. Over upper portions 272 and 273 of
each slide groove 270 and 271, respectively, each slide groove has
a forwardly directed upper rear surface 282 and 283 which is
vertical and spaced rearwardly from the respective front surfaces
280 and 281 by a first distance. Over a lower portion 274 and 275
of each slide groove 270 and 271, respectively, each slide groove
has a forwardly directed lower rear surface 284 and 285 spaced
rearwardly from the respective front surface 280 and 281 by a
second distance less than the first distance. The first distance
and the vertical dimension of the upper portions 272 and 273 of the
guide grooves 270 and 271 are selected so as to permit the
respective right and left latch members 48 and 49 carried on the
right and left cover side walls 22 and 23 to slide laterally
through the respective upper portions 272 and 273 of the slide
grooves 270 and 271 when the right and left locking members 48 and
50 are vertically and horizontally aligned with the upper portions
272 and 273 of the slide grooves 270 and 271 as occurs when the
cover assembly 14 is engaged on the housing assembly 16 in the
upper open position shown, for example, in FIGS. 27 and 31.
[0243] At least the intermediate portion 25 of the right cover side
wall 22 of the cover 18 is resilient and has an inherent bias to
adopt a right inherent condition as illustrated in all of the
Figures showing the cover 18 of the first embodiment. In FIG. 31,
the cover assembly 14 is in the upper open position relative the
housing assembly 16 and the right cover side wall 22 is laterally
to the right of the right housing side wall 200 and the right latch
member 48 extends through the right housing side wall 200 via the
upper portion 272 of the right guide groove 270. The right cover
side wall 22 is deflectable from the right inherent condition as
shown in FIG. 31 to right deflected conditions not shown in which
the intermediate portion 25 of the right cover side wall 22 is
laterally to the right of the right inherent condition. Similarly,
at least the intermediate portion 25 of the left cover side wall 23
of the cover 18 is resilient and has an inherent bias to adopt a
left inherent condition as illustrated in all of the Figures of the
first embodiment. In FIG. 31, the left cover side wall 23 is
disposed laterally to the left of the housing left side wall 201
and the left latch member 49 extends through the left housing side
wall 201 via the upper portion 273 of the left guide groove 271.
The left cover side wall 23 is deflectable from the left inherent
condition as shown in FIG. 31 to left deflected conditions not
shown in which the intermediate portion 25 of the left cover side
wall 23 is laterally to the left of the left inherent
condition.
[0244] From the condition of FIG. 31, by manually urging the
intermediate portions 25 of the left and right cover side walls 22
and 23 laterally outwardly away from each other, the right latch
member 48 and the left latch member 49 move laterally away from
each other laterally through and out of engagement with the right
and left upper portions 272 and 273 of the right and left guide
grooves 270 and 271 to assume the deflected conditions, with the
rod member 20 of the cover 18 is received in the rod receiving
slotways 260 and 261 in the right and left housing side walls 200
and 201 such that the cover assembly 14 is merely engaged with the
housing assembly 16 by reason of the rod member 20 being received
within the slot receiving slotways 260 and 261. While maintaining
the right and left cover side walls 22 and 23 in deflected
positions, the cover assembly 16 may be pivoted about the rod
member 20 within the rod receiving slotways 260 and 261 to pivot an
upper end of the cover assembly 14 forwardly until the right and
left latch members 48 and 49 are forward of the right and left
housing side walls 200 and 201. The right and left side walls 22
and 23 may then be released and permitted to return under their
inherent bias to the right and left inherent positions. The cover
assembly 14 is manipulated such that the rod member 20 is slid
downwardly in the rod receiving slotways 260 and 261 and out the
open ends 266 and 267 to totally disengage the cover assembly 14
from housing assembly 16 and assume a disengaged condition.
[0245] The first distance separating the front surfaces 280 and 281
from the upper rear surfaces 282 and 283 is sufficient to permit
the enlarged bulbous portions 56 and 57 at the distal inner ends 54
and 55 of the right and left latch members 48 and 49 to be slid
laterally outwardly through the upper portions 272 and 273 of the
slide grooves 270 and 271.
[0246] From the upper open position of FIG. 25, the cover assembly
14 is slidable relative to the housing assembly 16 to the lower
closed position as illustrated in FIG. 26 with the right and left
latch members 48 and 49 on the cover side walls 22 and 23 to slid
downwardly from the upper portions 272 and 273 of the slide grooves
270 and 271 into the lower portions 274 and 275 of the slide
grooves 270 and 271. In the lower portions 274 and 275, the second
distance between the front surfaces 280 and 281 and the lower rear
surfaces 284 and 285 is selected to be marginally greater than the
thickness of the reduced thickness portions 62 and 63 of the right
and left latch members 48 and 49 and less than the front to rear
dimension of the bulbous portions 56 and 57 at the distal inner
ends 54 and 55 of the right and left latch members 48 and 49. Thus
when in the lower closed position, the left and right latch members
48 and 49 are prevented from being moved laterally outwardly
through the lower portions 272 and 273 of the guide grooves 270 and
271.
[0247] Coupling of the cover assembly 14 to the housing assembly 16
is a reversal of the steps of removal described above. From a
condition in which the cover assembly 14 is separate, disengaged
and uncoupled from the housing assembly 16, the cover assembly 14
is manually moved so as to move the rod member 20 upwardly into the
opening ends 266 and 267 of the rod receiving slotways 260 and 261
and to then, with the upper end of the cover assembly 14, tilted
upwardly and forwardly from the rod member 20, slide the rod member
20 upwardly in the rod receiving slotways 260 and 261 until the rod
member engages the upper blind ends 264 and 265 of the rod
receiving slotways 260 and 261 with each of the right and left
cover side walls 22 and 23 disposed laterally outwardly of the
right and left housing side walls 200 and 201. Once the rod member
20 engages with the blind ends 264 and 265 of the rod receiving
slotways 260 and 261, the cover assembly 14 is pivoted about the
rod member 20 rearwardly at the same time that deflecting forces
are applied to each of the right and left cover side walls 22 and
23 to urge them laterally outwardly away from each other to adopt
the deflected condition such that with pivoting of the cover
assembly 14 about the rod member 20, the right and left latch
members 48 and 49 pass laterally outwardly of the right and left
housing side walls 200 and 201 to a position in which the right and
left latch members 48 and 49 are laterally aligned with the right
and left upper portions 272 and 273 of the right and left guide
grooves 270 and 271. When so aligned, the deflecting forces applied
to the right and left cover side walls 22 and 23 are released. Due
to the inherent resiliency of each of the cover side walls 22 and
23, on release of the deflecting forces, the right and left cover
side walls 22 and 23 move from the deflected condition to the
inherent condition with the right and left latch members 48 and 49
to pass laterally inwardly into the upper portions 272 and 273 of
the slide grooves 270 and 271 and assume the position shown in FIG.
25 with the cover assembly 14 is coupled to the housing assembly 16
in the upper open.
[0248] With the cover assembly 14 coupled to the housing assembly
16, the cover assembly 14 is vertically slidable relative the
housing assembly 16 from the upper open position of FIGS. 25 and 31
to the lower closed position shown in FIGS. 24 and 27. The cover
assembly 14 is shown coupled to the housing assembly 16 in the
lower closed position in FIGS. 24 and 27 as well, for example, in
FIG. 1. In moving between the lower closed position of FIG. 27 and
the upper open position of FIG. 31, the cover assembly 14 is
slidably guided relative to the housing assembly 16 by reason of:
(a) the rod member 20 on the lower portions 26 of the cover side
walls 22 and 23 being guided within the rod receiving slotways 260
and 261 in the housing side walls 200 and 201 concurrently with (b)
the left and right latch members 48 and 49 on the intermediate
portions 25 of the cover side walls 22 and 23 being guided within
the slide grooves 270 and 271 of the housing side walls 200 and
201.
[0249] In the lower position of FIG. 24, the cover assembly 14 is
retained in a latched manner in the lower closed position against
upward movement of the cover assembly 14 relative to the housing
assembly 16.
[0250] To move the cover assembly 14 relative to the housing
assembly 16 between the lower closed position of FIG. 24 and the
upper open position of FIG. 25, the user manually engages the
lifter member 500 and moves the lifter member.
[0251] Thus, as explained above, the cover assembly 14 is coupled
to the housing assembly 16 for movement between the lower position
and an open upper position. The housing assembly 16 has a
releasable cover latching mechanism to latch the cover 18 to the
housing 70 against vertical movement formed notably by the lifter
member 500 and its interaction with the housing 70 and the cover
18, and as well the housing assembly 16 has a lifting mechanism to
raise and lower the cover 18 relative the housing 70 formed notably
by the lifter member 500 and its interaction as in the manner of a
lever mechanism, preferably a cammed lever with a multiple pivot
points, with the housing 70 and the cover 18.
[0252] Reference is made to FIGS. 27 to 31, each of which is a
schematic left side view of the dispenser assembly of FIG. 4 in
different positions of the cover assembly between a lower closed
position, as seen in FIG. 27 and FIG. 28, and a fully open upper
position as shown in FIG. 31. In each of FIGS. 27 to 31, the bottle
reservoir 101 of the cartridge 15 is not shown. The pump assembly
100 is, however, shown. In each of FIGS. 27 to 31, each of the
lifting member 500 and the cover 18 are shown as being transparent
while the remainder of the components are shown in solid lines.
Showing the cover 18 and the lifting member to be transparent
assists in understanding, as seen in left side view, the relative
juxtaposition of these elements in the different positions and
conditions they can assume in movement between the lower closed
position and latched condition as shown in FIG. 27 to the lower
closed position and unlatched condition in FIG. 28, through the
first partially open position of FIG. 29, through the second
partially open position of FIG. 30 and to the fully open upper
position of FIG. 31. In both FIGS. 27 and 28, the cover 18 remains
in a lower closed position. In moving from FIGS. 28 to 31, the
cover is successively moved from the lower closed position of FIGS.
27 and 28 successively to the upper fully open position of FIG. 31.
As well, it can be seen that in a comparison of FIGS. 28, 29, 30
and 31, the lifting member 500 is from the position of FIG. 28
successively pushed downward and rearwardly with the lifting member
500 both pivoting about horizontal axes and pivot points as well as
having its stub axle 523 slide rearward in the slotway 511 of the
left housing side wall 201.
[0253] In understanding FIGS. 27 to 31, it is useful to understand
that as illustrated in the cross-sectional top view of FIG. 32 that
the components are being viewed from the left side in which, as can
be seen in FIG. 32, the left side wall 23 of the cover 18 is to the
left of the left arm 543 of the lifting member 500 which is to the
left of the left side wall 201 of the housing 70. Thus, as seen in
the top view of FIG. 32, the left arm 541 is in between the left
side wall 201 of the housing 70 and the left side wall 23 of the
cover 18.
[0254] Referring to FIG. 27, FIG. 27 illustrates the cover assembly
14 in the lower closed position and a latched condition. Absent the
lifting member 500, the cover assembly 14 including the cover 18
with its lever 19 and rod member 20 are free to be slid axially
upwardly relative to the housing assembly 16 between the lower
closed position and upper positions including the fully open upper
position of FIG. 31.
[0255] In each of FIGS. 27 to 31, the lifting member 500 is coupled
to the housing assembly 16 with the stub axles 522 and 523 of the
lifting member 500 slidably received within the slotways 510 and
511 of the housing 70. As seen in FIG. 27, the left stub axle 523
is spaced rearwardly from the front end of the left slotway 511 and
a rear end of the left arm 543 is located underneath the left
downwardly directed stop shoulder 535 of the left rear guide member
533. The left arm 541 overlies the rod member 20 with the rod
member 20 engaged in a downwardly directed forward concave recess
579 of the lower surface 565 of the left arm 543. In the position
of FIG. 27, the lifting member 500 is considered to be latching the
cover 18 against upward movement and thus providing a latched
condition to the dispenser assembly 10.
[0256] In moving from the position of FIG. 27 to the position of
FIG. 28, a user manually pulls the lifting member 500 forwardly as
shown by the arrow. As a result, the left stub axle 523 slides
forwardly in the slotway 511 to proximate the forward end 513 of
the slotway 511 and, in so doing, the rear end 563 of the left arm
543 is moved forwardly of the left rear guide member 533. In the
position of FIGS. 27 and 28, the lower surface 505 of the left
lifting flange 503 on the left side wall 23 of the cover 18 rests
on top of the upper surface 561 of the left arm 543.
[0257] In moving from the position of FIG. 28 to the position of
FIG. 29, the lifting member 500 is pushed downwardly and rearwardly
by a user indicated by the arrow. The lifting member 500 pivots
about its left stub axle 523 within the left slotway 511. Proximate
the rear end 563 of the left arm 543, the upper surface 561 engages
the left lifting flange 503 to slide the cover 18 vertically
upwardly relative to the housing 70. The lifting member 500 pivots
about its stub axle 523 within the front end 513 of the left
slotway 511 until the upper surface 561 engages a lower end 581 of
the left guide flange 531 as seen in FIG. 29. In moving from the
position of FIG. 29 to the position of FIG. 30, with the lifting
member 500 being pushed downward and rearward in the direction of
the arrow, the lifting member 500 pivots about the lower end 581 of
the left guide flange 531 until the upper surface 561 of the left
arm 543 is flush with the long straight section 583 of the left
guide flange 531 at which point the left stub axle 523 is ready to
move forwardly in the left slotway 511. The engagement of the end
surface 563 of the left arm 543 with the left lifting flange 503
moves the cover 18 vertically upwardly from the position of FIG.
29.
[0258] In moving from the position of FIG. 30 to the position of
FIG. 31, the lifting member 500 is pushed downwardly and rearwardly
as indicated by the arrow. The left stub axle 523 slides rearwardly
in the left slotway 511 as the upper surface 561 of the left arm
543 pivots about a pivot point at the corner 585 intermediate the
long straight section 583 and the short straight section 587 of the
left guide flange 531. The end surface 563 of the left arm 543
engages the left lifting flange 503 of the cover 18 to move the
cover 18 upwardly from the position of FIG. 29. The left stub axle
523 moves in the slotway 511 to the rear end 515 of the slotway 511
at a time when the upper surface 561 of the left arm 543 comes to
lie flush with the short straight section 587 of the guide flange
531 and into a bight 591 formed between the short straight section
587 of the guide flange 531 and a horizontal end portion 593 of the
guide flange 531. The upper end 561 of the left arm 543 engages the
lifting flange 503 to move the cover 18 upwardly to the open
position shown in FIG. 31. The lower surface 565 of the left arm
543 may engage the forwardly directed rear guide member 533 to
prevent further rearward movement of the lifting member 500.
[0259] In the condition shown in FIG. 31, the rear end 563 of the
left arm 541 engages the lifting flange 503 at an engagement
portion vertically forward of the stub axle 523. In this position,
the weight of the cover 18 acting vertically downward attempts to
rotate the lifting member 500 clockwise about the stub axle 523,
that is, in a direction away from a direction that the lifting
member 500 must move and rotate to permit movement of the cover 18
from the position of FIG. 31 to the position of FIG. 30.
[0260] Moving of the dispenser assembly 10 from an open position as
shown in FIG. 31 towards the closed and unlatched position of FIG.
28 is accomplished by a user pulling the front portion 540 of the
lifting member 500 upwardly and forwardly. The motion of the
lifting member 500 in moving from the position of FIG. 31 to the
position of FIG. 29 does not necessarily precisely duplicate the
relative motion that occurs as described above in moving from the
position of FIG. 28 to the position of FIG. 31. However, in
movement from the position of FIG. 31 to the position of FIG. 28,
the left arm 543 is maintained above the rod member 20 and
constrained to have its end surface 563 forward of the forwardly
directed rear guide member 533 at least by engagement with the rear
guide member 533. The lower surface 565 of the left arm 543 will be
maintained at least proximate its end surface 563 above the rod
member 20. In a case where the cover assembly 14 may become stuck
and may not under its own weight slide downwardly relative the
housing 70, the downwardly directed rear arcuate portion 577 of the
lower surface 561 proximate the end surface 563 of the left arm 543
will come to engage the upper surface of the rod member 20 and urge
the rod member 20 downwardly thus moving the rod member 20 and
hence the cover assembly 14 downwardly.
[0261] Reference is made to FIG. 23 illustrating a cross-sectional
view along longitudinal center line A-A' in FIG. 2 showing the
cartridge 15 coupled within the dispenser assembly 10 with the
cover assembly 14 in the lower closed position relative to the
housing assembly 16 in an operative condition ready for operation
of the dispenser assembly 10 to dispense fluid.
[0262] When the cover assembly 14 is in the raised upper position
relative the housing assembly 16 as seen in FIGS. 25 and 26, the
cartridge 15 is horizontally slidable rearwardly to engage with the
housing assembly 16 such that the bottle 101 comes to be received
within the interior compartment 46 defined within the housing 70
intermediate the housing left and right side walls 200 and 201,
forwardly of the back wall 202 and between the horizontal support
flange 202 and the bottle support flange 116 that bridges between
the housing side walls 200 and 201 with the bottom of the bottle
101 engaged and supported by a bottle support flange 116. The pump
mechanism 100 is slid rearwardly into engagement with the support
flange 202 of the housing 70 into the slot 205 of the support
flange 202 with the support plate 117 of the piston chamber-forming
body 110 above the support flange 202 between the horizontal
support flange 204 and the right and left vertical guide walls 120
and 121, and below the upper pump holding member 508. On moving the
cover 18 to the closed position, the piston chamber-forming body
110 is fixedly secured to the housing 70 between the support flange
202 and the upper pump holding member 508 against vertical
movement, and suitably located relative the pump actuator plate
75.
[0263] As shown in FIG. 23, the piston-forming element 111 is
disposed vertically below the pump actuator plate 75. To dispense
fluid with the dispenser assembly 10 in the orientation shown in
FIG. 23, a user engages the exterior handle portion 32 of the lever
19 and moves the exterior handle portion 32 of the lever 19
downwardly pivoting the lever 19 relative to the housing 70 about
the axle axis 35 which moves the forward ends of the right and left
actuator rods 42 and 43 of the interior actuator portion 33 of the
lever 19 downwardly causing the actuator plate 75 to slide
vertically downwardly against the bias of the left and right plate
springs 76 and 77 and move the piston-forming element 111
vertically downwardly relative to the piston chamber-forming body
10, dispensing fluid from the bottle 101 out the discharge outlet
113 onto a user's hand disposed underneath the outlet 113. On
release of the lever 19 by the user, under the bias of the left and
right plate springs 76 and 77, the pump actuator plate 75 returns
to the raised position and pivots the lever 19 to return to the
position shown in FIG. 22. The pump spring biases the
piston-forming element 111 to return to a raised position as shown
in FIG. 17.
[0264] The cartridge 15 is adapted to be removed and replaced
preferably by a new entire cartridge 15 as seen in FIGS. 25 and 26,
however, possibly with the bottle 101 being removed from the
cartridge 15 and refilled. Removal and replacement of merely the
bottle 101 is possible such as illustrated in FIGS. 39 and 40 when
the dip tube may be rigid the bottle 101 removed the pump mechanism
100 may be separately removed and replaced. Removal and replacement
is carried out with the cover assembly 14 in the upper open
opposition relative the housing assembly as seen FIGS. 25 and
26.
[0265] After use of the dispenser assembly 10 for periods of time,
portions of the dispenser assembly 10 which may be engaged by users
may become contaminated as with pathogens and the like. Preferably,
from time to time, the cover assembly 14 is removed from the
housing assembly 16 and the cover assembly may then be suitably
cleaned as preferably by being placed in an autoclave or washing
machine. The cover assembly 14 when cleaned may then be re-attached
to the housing assembly 16. Alternatively, a new or different cover
assembly 14 and a new or different lever 19 may be applied.
Coupling to or removal of the cover assembly 14 from the housing
assembly 16 is accomplished with the cover 18 and the lever 19
coupled together. After removal of the cover assembly 14 from the
housing assembly 16, the lever 19 can be removed from the cover 18
for separate washing and/or replacement. Separate washing of the
cover 18 and lever 19 is advantageous to clean the surfaces where
the axle keyhole openings 27 engage the axle 31.
[0266] Reference is made to FIGS. 42 to 48 showing a dispenser
assembly 10 identical to that illustrated in FIGS. 1 to 41,
however, additionally including a drip tray 600. The drip tray 600
is removably secured to the lifting member 500 in a snap-fit manner
as best seen in the cross-sectional side view of FIG. 47 showing
the upper edge of the forward portion 540 of the lifting member 500
engaged in a snap-fit between a rear tab 602 and a forward flange
604 carried on the underside of the drip tray 600.
[0267] The drip tray 600 is provided so as to catch excess fluid or
overspray of fluid that might be discharged from the dispenser
assembly 10 or that might drop from the pump outlet when the pump
is not in use. The drip tray 600 is configured such that when
coupled to the lifting member 500, the drip tray 600 and the
lifting member 500 may be moved through the positions of FIGS. 27
to 31 without interference with the remainder of the dispenser
assembly 10. The drip tray 600 is configured to be snap-fit onto
the lifting member 500 such that in the event excess forces are
attempted by a user to be applied to the lifting member 500 by a
user engaging the drip tray 600, the drip tray 600 will come to
disengage from the lifting member 500. The drip tray 600 is
advantageously removable and replaceable from the dispenser
assembly 10 as can be of assistance in reducing the volume of a
dispenser assembly 10 when shipped.
[0268] Reference is made to FIG. 33 which illustrates that at the
upper rear of the housing 70, an axle opening 700 is provided
defined to open vertically upwardly between a vertical front wall
701 and a vertical rear wall 702 closed by a bottom wall 703. As
can be seen in FIG. 33, the axle 31 of the lever 19 is removably
coupled within the upwardly opening axle opening 700 with the axle
31 becoming engaged with and removed from this axle opening 700
with vertical sliding of the cover assembly 14 relative to the
housing 70. As seen in FIG. 9, the lever 19 is removably coupled to
the cover 18 within the axle keyway opening 27 which opens
horizontally rearwardly. The cover 18 and the axle keyway openings
27 are also shown in FIG. 33. From FIG. 33, it can be seen that
when the cover 18 is in a closed position on the housing 70 that
the axle 31 is capt
